• This video teaches students about the chemical reactions that occur when the ocean absorbs carbon dioxide from the air, the pH scale, and the effects ocean acidification can have on marine organisms.
• There is an interactive quiz for students to check their understanding about ocean acidification and the pH scale.
  

Positives

• The video does a good job of explaining how carbon dioxide levels have risen in recent centuries because of humans.
• A full transcript of the video is available.

Additional Prerequisites

• Students should be familiar with the pH scale and ions.
  

Differentiation

• Chemistry classes could pause the video at 1:53 and challenge students to solve the chemical equation.
• Math classes could practice calculating the percentage difference between two pH numbers using logarithmic equations.
• Biology classes could use this video when discussing the pH scale, molecular bonds, homeostasis, the properties of water, ocean ecosystems, coral reefs, and chemical reactions. 
• Other resources on this topic include this video on the impacts of ocean acidification on marine life, 
  this video and experiment that shows how acidic environments dissolve calcium bicarbonate, and this experiment and lesson on determining the amount of carbon dioxide in ocean water.
